Title: Manufacture of slider for magnetic recording head
Inventor: YAMAZAKI KOJI
IPC: B28D5/00
Filed: 1988-10-03
Abstract: PURPOSE:To prevent the generation of the removal of particles from the surface layer part of a slider by a method wherein a slider block is heat-treated under the predetermined conditions of temperature, atmospheric pressure and humidity and, after that, cut with a cutting tool equipped with a grinding wheel having the predetermined particle size at the predetermined peripheral speed of the grinding wheel. CONSTITUTION:By heat-treating a slider block at 100 - 150 deg.C, the atmospheric pressure of 1.5 - 5kg/cm<2> and a humidity not higher than 60% for 3 - 20 hours, the possibility of the future removed of particles can be remarkably reduced. The possibility of the removal of particles gradually decreases in proportion to the rise of the treatment temperature until the temperature reaches 100 deg.C and the possibility of the release becomes small when the temperature exceeds 100 deg.C and becomes nearly zero at 150 deg.C. Next, when the atmospheric pressure at treatment is set within the range of 1.5 - 5kg/cm<2> and the humidity not higher than 60%, the possibility of the removal of particles can be lowered enough low. Further, in case that the treatment time is less than 3 hours, the possibility of the removal of particles is not improved so much. Furthermore, in case that the treatment time exceeds 20 hours, no change results in effect. Under the cutting conditions that a grinding wheel having the particle size of No. 1000 - 3000 is used on a cutting tool and the rotating speed of the grinding wheel is set at 3,000 - 10,000m/min, the surface roughness of a cut surface can be finished finer than 1mum.Rmax, resulting in confining the possibility of the removal of particles within the practical range.

CONSTITUTION:For a time division multiple video signal inputted from a signal input terminal 1, a recorded signal is selected by a recorded signal selection circuit 3. The recorded signal selection circuit 3 generates a velocity control signal and outputs it to a recorded signal processing circuit 4 and a servo circuit 8 based on the number of times for multiplexing the input time division multiple video signal, the transmission speed and the number of times for selective recording due to the recording select signal. In the case of reproduction, the velocity control signal is generated by detecting the number of times for multiplexing the recorded signal according to an ID signal contained in a regenerative signal, and this velocity control signal is transmitted to the servo circuit 8. Thus, regardless of the number of times for selectively multiplexing the recorded signal, all the recorded signal can be traced so that recording track patterns can be equal.

Abstract: PURPOSE:To inhibit the deterioration of a protection film and thereby constitute a long-life thermal head by increasing the thickness of a protection film on a thermal resistor in accordance with the heat distribution in the surface of the thermal resistor. CONSTITUTION:A thermal resistor 2 of Ta-SiO2 is formed on an electrically insulated substrate 1 by sputtering technique, and on this thermal resistor, an electrode film is formed that supplies power to the thermal resistor. Thus an electrode pattern is formed using lithography technique. On this pattern, a protection film layer 4 is constituted that inhibits the oxidation of the thermal resistor during heating and resists abrasion during printing. Generally, this protection film consists of two layers; a lower SiO2 layer as an oxidation inhibition layer and an upper Ta2O5 layer as an abrasion-resistant layer. The film is 5 to 8mum thick. Thus a thermal head is formed that has a circular protection film with a diameter of about 100mum in the center of the thermal resistor. Consequently, the life of a thermal head can be easily increased.
